Physical inactivity increases oxidative stress, endothelial dysfunction, and atherosclerosis.

2005

Objective— Sedentary lifestyle is associated with increased cardiovascular events. The underlying molecular mechanisms are incompletely understood. Reactive oxygen species (ROS) contribute to endothelial dysfunction and atherosclerosis. An important source of vascular ROS is the NADPH oxidase. Methods and Results— C57BL6 mice were subjected to regular housing (physical inactivity) or voluntary training on running wheels (6 weeks). Inactivity increased vascular lipid peroxidation to 148±9% and upregulated superoxide release to 176±17% (L-012 chemiluminescence) and 188±29% (cytochrome C reduction assay), respectively. ROS production was predominantly increased in the endothelium and the medi…

Wireless Strain Gauge Network : Best-Hall Measurement Case

2014

Wireless sensor networks can be used to perform structural monitoring. Strain gauges, which can be glued on or integrated to the observed material, are the most common nondestructive sensing elements for measuring surface strain. Wireless strain gauge measurement system makes strain measurements more flexible while opening new targets of application in addition to those that traditional wired strain measuring systems can offer. We have implemented a long term strain measurement in a PVC-covered hall using wireless sensor network. In this paper we evaluate the functionality and suitability of the developed wireless system for this kind of monitoring. The paper discusses the experiences gaine…

Computational aspects in checking of coherence and propagation of conditional probability bounds

2000

In this paper we consider the problem of reducing the computational difficulties in g-coherence checking and propagation of imprecise conditional probability assessments. We review some theoretical results related with the linear structure of the random gain in the betting criterion. Then, we propose a modi ed version of two existing algorithms, used for g-coherence checking and propagation, which are based on linear systems with a reduced number of unknowns. The reduction in the number of unknowns is obtained by an iterative algorithm. Finally, to illustrate our procedure we give some applications.

Algorithms for coherence checking and propagation of conditional probability bounds

2001

In this paper, we propose some algorithms for the checking of generalized coherence (g-coherence) and for the extension of imprecise conditional probability assessments. Our concept of g-coherence is a generalization of de Finetti’s coherence principle and is equivalent to the ”avoiding uniform loss” property for lower and upper probabilities (a la Walley). By our algorithms we can check the g-coherence of a given imprecise assessment and we can correct it in order to obtain the associated coherent assessment (in the sense of Walley and Williams). Exploiting some properties of the random gain we show how, in the linear systems involved in our algorithms, we can work with a reduced set of va…

Jet fragmentation transverse momentum distributions in pp and p-Pb collisions at √s, √sNN = 5.02 TeV

2021

Jet fragmentation transverse momentum (jT) distributions are measured in proton-proton (pp) and proton-lead (p-Pb) collisions at √sNN = 5.02 TeV with the ALICE experiment at the LHC. Jets are reconstructed with the ALICE tracking detectors and electromagnetic calorimeter using the anti-kT algorithm with resolution parameter R = 0.4 in the pseudorapidity range |η| < 0.25. The jT values are calculated for charged particles inside a fixed cone with a radius R = 0.4 around the reconstructed jet axis. The measured jT distributions are compared with a variety of parton-shower models. Herwig and Pythia 8 based models describe the data well for the higher jT region, while they underestimate the low…

related to the perturbative component of the fragmentation processthe measured trends are successfully described by all models except for Herwig. For the wide componentHerwig and PYTHIA 8 based models slightly underestimate the data for the higher jet transverse momentum region.

The jT distributions are further characterised by fitting them with a function composed of an inverse gamma function for higher jT values (called the “wide component”)predominantly connected to the hadronisation process.

COPE-indeksillä mitatun omaishoitajan kuormittumisen tilan yhteys omaishoidettavan käyttämien sijaishoitopalveluiden määrään ja käytön useuteen

2013

On olemassa vahva yhteisymmärrys siitä, että ikääntyneen henkilön omaishoitaminen voi olla kuormittavaa. Omaishoitoa tuetaan erilaisilla sijaishoitopalveluilla. Niiden vaikutuksista omaishoitajien kuormittumiseen ei kuitenkaan olla yksimielisiä. Sijaishoitopalveluiden käyttömäärissä ja käytön useudessa on suuria vaihteluja omaishoidettavien välillä. Tämän tutkimuksen tarkoituksena on selvittää COPE-indeksiä (Carers of Older People in Europe, COPE index) apuna käyttäen, minkälainen on omaishoitajien kuormittumisen tila Jämsä-Kuhmoinen SoTe-yhteistoiminta-alueella. Lisäksi tutkimuksessa selvitetään, onko omaishoitajien kuormittumisen tila yhteydessä omaishoidettavan käyttämien sijaishoitopalv…

Fear of Childbirth, Self-Esteem and Birth Experiences: Pregnancy and Postpartum

2022

This dataset contains all three phases of data collection from the survey study Fear of Childbirth, Birth Experiences, Self-Esteem and Parental Burnout. The data contains answers from participants (n=125) in late pregnancy (30+ weeks in gestation) and postpartum (4-8 weeks after childbirth and 1 year after childbirth). The data is collected in 2020-2021 from four Finnish cities. Participants have completed background information (in pregnancy), fear of childbirth scale (W-DEQ, all three time points), Rosenberg self-esteem scale (all three time points), and Delivery Satisfaction scale (only 4-8 weeks postpartum). In addition, the data contains variables such as depression (BDI), satisfaction…

EFFECTS OF SHIFT WORK ON CARDIOVASCULAR ACTIVITY, SERUM CORTISOL AND WHITE BLOOD CELLS COUNT IN A GROUP OF ITALIAN FISHERMEN

2012

We analyzed the effects of working activity and working shifts on the circadian rhythmicity and circadian phase relations of serum cortisol level, white blood cells count, resting heart rate and systolic/diastolic blood pressure in a group of italian fishermen. We observed a shift-induced displacement of cortisol secretion and a modification in leukocyte count. Moreover, systolic/diastolic blood pressure and resting heart rate were markedly influenced by the night shift, whereas no appreciable changes were observed after the morning and afternoon shifts, compared to pre-working values. These data suggest that the human circadian system is greatly influenced by shift work, and serum cortisol…
